The "New Energy Outlook" report, released finds that at least $11.4 trillion will be invested in new power-generating capacity over the next 25 years, and 60 percent of that will fund wind and solar power. According to the report, we'll reach a tipping point in 2027, when new wind and solar power actually become cheaper than running existing coal and gas generators in much of the world. This will cause an acceleration in the deployment of clean energy technologies.
